Problems solved by technology

However, there are few reports on the knowledge map of financial activities of listed companies in the market
[0003] At present, the construction of knowledge graphs in the industry mostly relies on manual construction, which consumes a lot of labor costs
The main reason is that the existing automated construction technology is difficult to apply to different fields, and it is often necessary to design a targeted automated knowledge map construction method for a specific field

Abstract

The invention discloses a risk analysis method for a listed company financial activity knowledge graph. The method comprises the following steps: constructing a financial activity knowledge graph; normalizing all named entities in the named entity library; on the basis of the named entities subjected to the standardized processing, constructing a triple, and further obtaining a triple candidate set; obtaining an effective triple according to the triple candidate set; constructing a knowledge graph according to the effective triple; performing knowledge graph risk analysis; constructing a financial risk conduction model according to the knowledge graph; performing iterative calculation to obtain a converged financial risk conduction model, where the model is used for representing the potential risk degree of each named entity in the knowledge graph. According to the invention, the defect that in the prior art, a knowledge graph needs to be constructed manually is overcome, a large amount of labor cost is saved, the financial risk conduction model is constructed, named entities with potential risks in the knowledge graph are mined, and the method plays an important supporting role in strengthening supervision of market financial activities by listed company supervision organizations.

Description

technical field [0001] The invention belongs to the technical field of knowledge map risk analysis, and in particular relates to a risk analysis method for a listed company's financial activity knowledge map.
